water disinfection TOC Applications

Total Organic Carbon (TOC) is found in all water supplies as naturally occurring organic matter. Over many years of experience, medium or low pressure UV treatment has become recognised as an effective process step in the breakdown and reduction of TOC in water intended for use in pharmaceutical, health care, power generation and micro-electronics applications. In the latter case, ultra-pure water is used to wash silicon wafers on which even small deposits of carbon compounds on the wafers can severely affect...

Water is often used as a product, or as part of the manufacturing process. In many industrial applications, processes are chemical (chlorine) intolerant, and UV is widely adopted. atg UV Technology engineers will be pleased to discuss solving disinfection problems with you. As well as a powerful disinfectant, UV is used to remove chlorine, chloramines, ozone, bromine, and a wide variety of contaminants from industrial process water. Within micro-electronics facilities for example, UV is used to remove Total...

Problem: Organic matter (UV254/TOC) in drinking water can react with chlorine to form harmful disinfection by-products (DBPs). Some removal of TOC is achieved through the conventional drinking water treatment processes, while carbon absorption may be used to further enhance the removal of TOC prior to chlorine disinfection.

atg UV Technology have a range of systems specially designed for the production of high quality ultra pure water for use within a range of pharmaceutical and electronic production (semi conductors) applications. Ultrapure Water TOC Reduction De-Chlorination Ozone Destruct.

Advanced Oxidation reactions are an extension of the process whereby UV alone is used to reduce Total Organic Carbon (TOC) through the lysing of water molecules into hydroxyl radicals. Hydroxyl radicals (OH) are produced with the help of one or more primary oxidants (usually ozone or hydrogen peroxide) and ultraviolet light. This reactive species is the strongest oxidant that can be applied in water and can oxidize virtually any compound present in the water.
